Easy way would be to just airmon-ng stop wlan0, ifconfig down mon0, /etc/init.d/NetworkManager restart and click on the little green little blob in the right hand cornnor to connect. Enter your key like 00:11:22... like 001122...
or use a script like this one http://forums.remote-exploit.org/showthread.php?t=22287
